BACKGROUND AND PURPOSE An effective intervention has not yet been established for patients with acute ischemic stroke who present with serious neurologic symptoms due to occlusion or a high-grade stenosis of the internal carotid artery (ICA). The aim of our retrospective study was to investigate the feasibility, safety, and efficacy of emergency carotid(More)
BACKGROUND Several studies have reported that cilostazol (CLS) may reduce in-stent restenosis (ISR) after carotid artery stenting (CAS). However, it is not known for how long CLS must be continued to prevent ISR. METHODS We retrospectively reviewed a prospectively collected database of patients who underwent elective CAS and follow-up angiography at 3(More)
An early 60s-year-old man suffered reversible dysfunction of the blood-brain barrier (BBB) induced by repeated injection of contrast medium during coil embolization of intracranial unruptured aneurysm. He presented with convulsion during coil embolization, and neurological symptoms of aphasia and right hemiparesis continued for 5 days, and then improved(More)
PURPOSE To report an important complication related to carotid stenting. METHODS AND RESULTS A 71-year-old man with symptomatic subtotal occlusion of the left internal carotid artery had a 30-mm lesion treated percutaneously with implantation of 2 stents. Although the procedure was completed satisfactorily, left intraventricular hemorrhage occurred 4(More)
PURPOSE To report a case of successful stenting after a subacute stroke. CASE REPORT A 75-year-old man presented with sudden onset of right-sided weakness and difficulty speaking. Imaging revealed an occlusion of the left petrous to lacerum internal carotid artery (ICA) segment and slightly decreased cerebral blood flow in the left hemisphere; there were(More)
The efficacy of endovascular interventions based on magnetic resonance (MR) imaging for acute ischemic stroke caused by embolic carotid T occlusion was assessed. Endovascular intervention was performed in 10 of 751 consecutive acute ischemic stroke patients admitted to our institution between April 2001 and July 2003. Indications were: presentation within 6(More)
BACKGROUND AND PURPOSE The purpose of our retrospective study was to investigate the feasibility, safety, and efficacy of clot removal therapy by aspiration and extraction for patients with acute stroke with embolic internal carotid artery (ICA) occlusion. METHODS Of 814 consecutive patients with acute ischemic stroke admitted to our institution from(More)
Pineal parenchymal cell tumors (PPCTs) with or without metastasis into the lumbar region by way of the cerebrospinal fluid were treated successfully with combination chemotherapy using cisplatin, vinblastin, and bleomycin (PVB) or cisplatin and vinblastin (PV) and low-dose irradiation (25∼30 Gy). Our series included a case of pineoblastoma, two cases of(More)
BACKGROUND Hyperperfusion syndrome (HPS) is a critical complication after carotid artery stenting (CAS) and carotid endarterectomy (CEA). OBJECTIVE To identify predictors of HPS before and immediately after CAS. METHODS We analyzed patients who underwent elective CAS from 2005 to 2008, and underwent single-photon emission computed tomography (SPECT) and(More)
BACKGROUND A study was undertaken to investigate the feasibility, safety and effectiveness of emergency carotid artery stenting (eCAS) for a high-grade carotid stenosis with intraluminal thrombus (ILT) with or without proximal flow control (PFC). METHODS Patients with acute ischemic stroke included in the analysis were those who were admitted between 2001(More)
